ROTATIONAL FUEL FEED FOR COMBUSTION CHAMBERS Filed May 7, 1947 a Jamil? dd W535?" ssmm q green-gt v a combustion ropulsion appacombustion liquids in such manner that they will receive rotational movement around anjannular intake channel as theyenter the combus- ,tion chamber.

A further object is to-provide means by which It fis -ithe general ob ect oi 'tlle invention. to? provide improved means for feeding two diiierent tthe two liquids will rotate asalternated and y superposed films withinsaidannular channels.

I An important featuraof the invention relates I .to the provision of partition means inthe annuwhich the two combustion. liquids maybe injected'; j and relates more specifically to the 'provision of a partitionof serpentine formation, ,which permits the two liquids to be'injected at successive points along the center, line of the annular channel, while at'the same time they .are injected at opposite sides of the partition.

lar channel, adjacentthe two opposite sides of v nerof the combustion liq v gen, is in roduced thro la pipe 2 0: (Fig.1) to a hollow casing 2| forming a jacket spabegfl be-Q, tweensaid casing 2| and the inner end'jportion 24 0i the chamber C. The casingfZl jextends arou'nd-theerid of the chamber C as shown in; Figs. l and -3,;andthe jacketspace-IZ thus com-" ,municates directlywith the portsior openingsl 'The other combustio iquid, as gas oline, s
